AXA estimates its exposure to stricken US company Enron at about Euros 200m (£125m).
The exposure is comprised of fixed income securities rather than insurance contracts.
The French group announced the figure after a complete review of its portfolio as it stood on 28 November.
It had previously reported that it had no significant exposure through investments in Enron's shares.
Enron is reported to be trying to find a financial partner to help it rescue some of its core activities.
The Houston-based firm filed for protection from its creditors after a rival firm pulled out of a rescue merger.
Investment banks JP Morgan Chase and UBS Warburg are today reported to have registered an interest in forming a joint venture with Enron to take over its energy trading business.
